Abstract

The present invention relates to a pneumatic shock absorber,
It is general that most of pneumatic shock absorbers having the function of a buffer in the cylinder system have a piston-type coupling process.
Therefore, conventionally, a piston is always coupled to a piston of a pneumatic shock absorber. The combination packing is the most important technique for pneumatic shock absorber because it is used to block the pressure inside the cylinder and to preserve the pressure inside it. It was a process of technology that could neither reduce nor improve the frictional force of the cylinder and the inner diameter of the cylinder. Thus, the present invention has been made to increase the function of the pneumatic shock absorber by changing the manufacturing process of the conventional pneumatic shock absorber, and is an air pressure cylinder shock absorber which is a cylinder type manufacturing structure like the conventional pneumatic shock absorber. Can be explained as follows.
The rubber hose with elasticity is made of a closed rubber tube, and the closed rubber tube is inserted into the outer cylinder and the inner cylinder to connect both ends of the two cylinders to the both ends of the hermetically sealed rubber tube, A technical process is performed in which air is injected into the rubber tube and the function of the shock absorber is obtained by using the force of air pressure injected into the sealed rubber tube. One problem can be posed here because it is judged that it can not be manufactured because the sealed rubber tube is blown if the air is injected into the closed rubber tube or because the two cylinders are separated from each other, The above problem can be solved because the wire rope capable of withstanding a certain pressure is combined in the process. It is difficult to grasp the advantages and disadvantages of the pneumatic shock absorber, which is a process of new technology. However, it is considered to be a technological process that is not insufficient to supplement the defects of the conventional pneumatic shock absorber. This simple coupling method is characterized by having the function of a pneumatic shock absorber.

Description

Pneumatic shock absorber {omitted}

The present invention relates to a pneumatic shock absorber, and more particularly, to a pneumatic shock absorber which is made so that an air pressure is injected into a shock absorber to function as a shock absorber by force of an air pressure injected into the shock absorber .

Generally, two kinds of shock absorbers are used as shock absorbers.

One is a coil type shock absorber, and the other is a cylinder type shock absorber. The present invention is a cylinder-type shock absorber and is a pneumatic shock absorber that is constructed in such a manner that air pressure is injected into the shock absorber and the function of the shock absorber is obtained by using a change in air pressure injected into the shock absorber. In the conventional air pressure shock absorber, a packing is combined with a piston in order to prevent a pressure from leaking to the outside of the cylinder. Packing coupled to the piston functions to compress the inner diameter of the cylinder by the motion of the piston and preserve the pressure inside the cylinder while preventing leakage to the outside. As a result, the pressure inside the cylinder is leaked to the outside and the function of the pressure buffer is lost.

In order to overcome such disadvantages, the present invention is characterized in that the piston and the packing are not combined in the cylinder of the pressure shock absorber, but the rubber hose having elasticity is used to manufacture the hermetically sealed rubber tube, And air is injected into the sealed rubber tube. By the movement of the two cylinders, the pressure of the air pressure injected into the rubber tube due to the change in the volume of the sealed rubber tube, The present invention has been made for the purpose of advancing the function of the conventional air pressure shock absorber by making it possible to have the function of the shock absorber by using the force.

Therefore, unlike the conventional technique of manufacturing the air pressure buffer according to the present invention, in which the piston with the packing is moved and the function of the shock absorber is changed by utilizing the change in the pressure inside the cylinder, So that the volume of the rubber tube hermetically sealed within the two cylinders is reduced while the pressure inside the rubber tube is increased so that the rubber tube can function as a shock absorber. In the conventional pneumatic shock absorber, Since the packing is not coupled, the frictional force and the resistance are reduced, and the function of the buffer is improved. The surface of the packing is pressed against the inner diameter of the cylinder, and the surface of the packing wears, And the leakage of the external force causes the function of the shock absorber to be lost.

Conventionally used pneumatic shock absorbers are combined with piston and rubber packing in order to prevent pressure from leaking out to the inside of the cylinder. The rubber packing joined with the piston is connected with the piston for the purpose of preventing the pressure from leaking out to the inside while moving by being pressed against the inner wall of the cylinder by the piston, There is a disadvantage in that when the surface of the packing is worn out, the pressure is leaked to the outside and the function of the buffer is lost.

Therefore, the rubber packing bonded to the piston plays an important role in determining the function and service life of the pneumatic shock absorber. However, the function of the shock absorber is deteriorated due to the frictional force generated by movement of the inner wall of the cylinder, It is difficult to compensate for the disadvantage that the use function is lost. This is because it has to be a method of manufacturing pneumatic shock absorbers by new technology.

In order to solve this problem, the present invention is a pneumatic shock absorber manufactured by a new technique, and a rubber hose having elasticity is used instead of packing with a piston which is conventionally coupled to the inside of the pneumatic shock absorber, The rubber tube is inserted into the cylinder and is combined with the rubber tube to reduce the volume of the sealed rubber tube by the force applied by the cylinder, It is expected that the problems caused by the pneumatic shock absorber will be significantly reduced and its function and service life will be significantly improved as compared to the conventional pneumatic shock absorber.
